Debevoise & Plimpton, Hogan Lovells and Weil Gotshal & Manges are among a line-up of top law firms to have advised on the $24.4bn (£15.5bn) buyout of computer manufacturer Dell, in the largest leveraged buyout (LBO) since the financial crisis.

Founder Michael Dell is buying back the PC group, together with private equity group Silver Lake, offering stockholders $13.65 (£8.69) in cash per share.

Dell, who holds the chief executive and chairman posts at the company, already owns an estimated 14% of the Fortune 500 giant, which last year took in revenue of $62.1bn (£39.5bn).

The company instructed Hogan Lovells' US arm for the LBO, while Wachtell Lipton Rosen & Katz represented Michael Dell, with Simpson Thacher & Bartlett acting for Silver Lake.

Hogan Lovells' team was led by securities partner Richard Parrino and corporate partner Kevin Greenslade, supported by corporate partners Joseph Connelly, Bruce Gilchrist and Eve Howard, finance partner Peter Humphreys and M&A partners Carine Stoick and Brent Singley. Partner Margaret de Lisser advised on employee benefits, while partner Todd Overman provided advice on government contracts. Paris-based partner Dominique Mendy acted on European labour law aspects.

Clifford Chance also took a role, acting for Silver Lake as European and Asian legal counsel with a team led by corporate partner Thijs Alexander.

Debevoise acted as legal adviser to the special committee of the company's board of directors with a team comprising corporate chief Jeffrey Rosen, M&A co-head Wiiliam Regner, corporate partner Michael Diz, head of executive compensation and employee benefits Lawrence Cagney, tax partner Peter Furci, litigation partner Gary Kubek, corporate partner Pierre Maugue and corporate partner Jeffrey Ross.

Debevoise previously advised Dell on its $1.15bn (£730m) acquisition of data-storage provider 3PAR in 2010, with Rosen leading the team on the transaction.

Weil represented Evercore Partners, one of the financial advisors to the committee, with a team led by New York corporate partner Michael Aiello alongside corporate partner Matthew Gilroy.

The American Lawyer reports that Sullivan & Cromwell corporate partner Alison Ressler is leading a Los Angeles-based team from the firm advising Microsoft, which has contributed a loan to help finance the purchase, while Davis Polk & Wardwell corporate partner Alan Denenberg is leading a team representing JP Morgan Securities in its role as the other financial adviser.

The takeover, which is subject to regulatory and Dell stockholder approvals, is expected to close before the end of the second quarter of Dell's 2014 financial year.
